I prepared a few more pots for the growbed. Soldering iron is the best and quickest way to make the holes.
I am using Baba's RD-150 pots and I had to weight them down with a pebble because they are so very light.
I also had to make a net bed to stop the media from escaping from the huge holes at the bottom of the pots.
I now have 2 pots of Bak Choy and I just transplanted a Kailan.
I definately need more pots and Leca as media.
